Abnormal Leadership

Addressing the cybersecurity threat landscape was never going to be simple. So our founders took an unconventional approach to the traditional security model, using their experience in behavioral modeling from the AdTech industry to transform traditional security.

We reimagined how to secure cloud email—the most broadly used channel, subject to the most sophisticated attacks. This foundation in unconventional thinking is at the core of our innovation to achieve our mission of making the cloud a safer place for businesses. Equally important is our commitment to customers. We listen, we learn, and we build products to protect them from the most advanced attacks. We are committed to transforming cloud security, safeguarding our customers, and delivering an unprecedented customer experience.
